MANUFACTURE OF CONCENTRATED TOBACCO EXTRACT.

Specification of Letters Patent.

Patented se t. 29, 1908.

Application filed January 10, 1908. Serial No. 410.210.

To all whom it mtcy concern:

lie it known that I, thuns'rmx FRIEDRICH (iLors'n-nx, a subject of the German Empire, rcsidin; at Henderson. in the county of liendcrson and State of Kentucky, have invented a new and useful Improvement. in the Manufacture of Concentrated Tobacco Extracts, of which the following is a specilication. y

The invention eonsistsof an improved method of treating raw aqueos tobaccoextract. whereby I obtain an extract free from sediment.

ltaw aqueous tobacco extract. usually contains in addition to suspended dirt, incident. to the pro "ss of obtainine the extract, a certain quantity of albumen, which when the extract is concentrated forms an nude sirable precipitate. I have discovered that this prwipitation may be readily avoided by converting the albumeninto peptones, etc.

The method consists in heating the raw aqueous tobacco extract to a' temperature above Jon t. and under pressure until the albnmens have been tran formed into peptoncs. I have found that if the temperature bc raiscd to about Hill and the pressurebe kept at about 100 pounds to the. square inch. the 1ranstornnition of the albumcns, whether lbc are contained in the extract in dissolved or undissolred condition, is completc'in about an hour. The same result ma 1c obtained although the temperature and ircssurc be raricd provided the tcmpcrat-urc be ktpt alnn'c ltltl (I In the accompanying drawin; is shown in side oictation partly broken away, a simple apparatu for calvine out the prta-ess.

trong tank A. prcl'c ably made of steel is )rorided with heating coils. I). of copper or rass. a gage c. a man-hole II, and convenicut inlcts and outlets for the extract, c and f rcsptartirely. I

The tank. A. is tilled to one-half or threcfourths of its capacity with raw aqueous tobacco extract. Then steam of sullicient pressure. is applied to the heating coil, I). until the tobacco extract .has reached the tclnperature ofahout 160 and there is a pressure of about 100- )ounds to thesquale .-inch on the tank. whici will be shown by the gage. c. The heat and pressure is now kept constant for about an hour. After the steamis cut otl and the tobacco extract .sufliciently cooled down, the extract can be drawn o'ti' and filtered. to be cleaned of its suspended dirt. and then concentrated. In the same manner the precipitated albumen of-a tobacco extract, if mixed with :i sullicient quantity of water. for example one pound water to one pound sediment of albumen and treated as above described, can be dissolved again and will sla \'.tl-issol\'c (l forever.

I claim as my invention:

1. The process of treating tobacco extractwhich consists in subjecting the same to a temperature abov loo t, under Pressure to transform the albumens pre ent into pcptones.

'lhtnprta-ess of treating lulnhfco extract which consists in heating the s: me to a temperature of approxilnatcly l'iut. under a pressure of approximatclr to!) ounds to the square inch for about one hour. to translorm the albulncns present into pcploncs.

I-l. .\s a new product. a tobacco extract having its normal albumcns pc-ptonizcd to prercnt sediment. i
